Utilizing seawater samples collected during the summer of 2025 in the Dingzi Bay region, South Yellow Sea, this study conducted a comprehensive analysis of the contents and concentrations of dissolved gases (N2, O2, Ar, CO2) and hydrocarbon gases (such as methane, ethane, and propane). The findings reveal that the dissolved gases in the study area are predominantly composed of N2 and O2, with average proportions of 77.8% and 2...

Corrosion of reinforcing steel exposed to chloride leads to the degradation of steel-reinforced concrete structures. Electrochemical chloride removal (ECR) has proven to be a non-destructive and cost-effective rehabilitation technique for reinforced concrete structures. Most studies have focused on chloride attack, with free chloride removal efficiency used as the primary index to measure ECR performance. Hence, we focused on...
